DISPLAY LDEVIGE.-

Application filed November 3, 1925. Serial No. 66,583.

This invention relates to a display device.

An object of the invention is to provide a simple and efficient device whereby a series of advertisements can be successively displayed through a suitable opening in the casing, and illuminated selectively by colored lights, the only thing being required of the operator is that he turn on the current, the operation thereafter being entirely auto: matic.

. The invention is illustrated in the drawings, of which Figure 1 is a section taken on the line 11 of Figure 2. I

Figure 2 is a sectiontaken on the line 2-2 of Figure 1.

Figure 3 is a section taken on the line 3-3 of Figure 2.

Figure 4 is a section taken through the opposite end of the drum shaft showing the pawl and ratchet arrangement for intermittently releasing the drum.

Figure 5 is a. longitudinal section taken through one end of the drum showing the manner in which it is mounted for rotation.

Figure 6 is an elevation of the casing.

Considering the device in its general aspect it comprises a casing within which is mounted a motor. This motor is adapted .to continuously operate a shaft which carries a pinion and a disc. The pinion, meshing with a gear and the disc having a pin thereon which is adapted to intermittently actuate a latch pawl. The gear is connected to a rotatable element associated with a drum on which the advertisements are dis- 'posed on a series of faces thereof. The

connection between the rotatable element and the drum is only through the intermediary of a-spring. The latch pawl engages a ratchet member on the drum and When released will permit the spring above mentioned to move the drum in a complete circular movement. The latch pawl is released immediately after being actuated and engages another tooth on the ratchet, so that the drum is moved step by step through the action of the pawl, whereas the motor shaft and gear are continuously operated. -The drum shaft carries commutator devices whereby certain lights within the drum can be selectively illuminated.

The preferred form of this invention comprises a casing having a base plate 10- and a front wall 11, in which is disposed a transparency 12. \Vithin the casing on the base plate is mounted the motor 13. -The pulley .14 of thismotor is'connected by a belt to. a pulley 16, mounted on a shaft 17 carrying a worm 18, meshing with a worm gear 19 on a shaft 20. This shaft also carries a disc 21 having a pin 22 thereon. The other end of the shaft is pivoted with a pinion meshing with a gear 24 mounted on a rotatable sleeve 25. This sleeve 25 is rotatably mounted on a sleeve 26. The sleeve 26 supports a drum 27 having a plurality of faces on which advertising matter is disposed. At the other end of the drum 27 is a sleeve 28 which also supports the drum 27. The manner in which the sleeves 27 and 28 support the drum is clearly, indicated in Figure 5 which shows a construction for one sleeve, which is identical with the construction of the other at .the other end of the drum. The sleeve 28 is shown in Figure 5 and is connected to the drum 27 On the sleeve 28 is also mounted a commutator plate 29 having contact elements 30 thereon. Also pinned to the side of the drum and mounted on the sleeve 28 is a ratchet member 31. The sleeve 28 is mounted for rotation on a fixed sleeve 32,

which is preferably hollow and forms at one end a socket 33 for a lamp 34, which projects into the drum 27."

The wires 35 from the lamp extend through the fixed sleeve 32. This fixed sleeve 32 is mounted on a bracket member 36 supported from the base plate 10. The

construction of the sleeves at the other end of the drum is substantially identical. In this case a commutator element 37 is pro vided with contact pieces 38 and the sleeve 26 is rotatably mounted on a fixed sleeve 39 supported in. suitable brackets such as 40, said fixed sleeve also acting as a socket for lamp 41. Disposed on the brackets at the left end of the drum as shown in Figure 2 are a pair of switch fingers 42 and 43. Disposed on the brackets at the other end of the drum are a pair of switch fingers 44 and 45. These pairs of switch fingers are adapted to be bridged by the contact pieces 30 and 38 to close the circuits which will hereinafter be mentioned.

Mounted on the brackets 36 is a latch pawl 46, one end of which is adapted to be engaged by the pin 22 and the other end of which is adapted to engage the teeth 47 on the ratchet member 31.

In the operation of the device a plug 48 is inserted into a socket 49 at the rear of the casing, as shown in Figure 2. This connects the electrical part of the apparatus, which operates as follows: The current flows through the wires 50 and 51 to energize the motor 13. The circuit for the lamp 41 is as follows: Wire 52 to the lamp 41, out through wire 53 to the switch finger 45, across contact element 38, through switch finger 44, into wire 54, then to return wire 55, leading back to the other side of the circuit 49.

The circuit for the lamp 34 is as follows: From socket 49 through wire 56 into the lamp, then out of the lamp through wire 57, through switch finger 42, contact element 30, switch finger 43, wire 58, then to return wire 55 to the other side of the circuit 49.

The motor is operated continuously and this operation rotates the shaft continuously, causing the pinion 23 and the gear 24 to operate continuously. This will rotate the sleeve 25 continuously around the sleeve 26.

This sleeve or element 25 is connected to one end of a spring 59, the other end of which is connected to the sleeve 26 as shown in Figure 3. Therefore, as the rotatable element 25 moves and while the drum 27 is being held from rotation by the pawl 46, the spring 59 is being wound up but as soon as the pawl is removed from engagement with the teeth 47 on the ratchet member 31, this spring will be unwound and in so doing will step the drum around until the pawl en'gages the next tooth on the ratchet. When the drum is released these two supporting sleeves 26 and 28 will only rotate on the sleeves 32 and 39, and this rotation will cause the movement of the commutator elements Which carry the contact pieces 30 and 38. These contact pieces therefor are brought successively into engagement to bridge the spring fingers above mentioned and the lights are therefore alternately illuminated and extinguished. The angular relation between the two commutator plates may be varied so that as one light is illuminated the other is extinguished. It is furthermore obvious that these light-s may be of difierent colors. It is also obvious that after the plug has been inserted in the socket, the device, outside of being oiled occasionally, needs practically no attention and will operate automatically.

What we claim is:

A display device which comprises a motor a shaft continuously driven by said motor, a pinion on said shaft, a gear operated by said pinion, a drum on which advertising matter is displayed, a spring disposed between the drum and the gear, a ratchet on said drum, a pawl engaging with said ratchet, a plate on said shaft, a pin on said plate adapted to engage said pawl asthe shaft rotates to release the pawl from the ratchet and permit the spring to operate the drum.
